GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 664,355, dated December18, 1900.

Application filed May 14, 1900. Serial No. 16,604. (No model.)

To a/ZZ whom, t may concernj Be it known that I, JOHN P. JOHNSTON, acitizen of the United States, residing at Oak Park,in the county of Cookand State of Illinois, have invented certain new and 'usefulImprovements in Gas Apparatus, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to apparatus used in the manufacture of water-gas.In gas apparatus of this character it is usual to supply the oil to thecarbureter through feeding or spraying devices arranged in acarburetingchamber, and consequently subjected to the heat thereof, theresult being that the oilfeeding apparatus is soon burned out and has`to be replaced. This, Ihave discovered, can be avoided by providing forautomatically withdrawing the oil-feeding devices from thecarbureting-chamber when they are not in use. This I accomplish ashereinafter described and as illustrated in the accompanying drawings.What I regard as new will be set forth inthe claims.

In the accompanying drawings, Figure 1 is a sectional view of the upperpart of a gen erator, a carbureter, and asuperheater, illustrating myinvention; and Fig. 2 is an enlarged view, being a partial sectionalView on line 2 2 of Fig. 1.

Referring to the drawings, 1 indicates a gas-generator; 2, a carburetorcommunicating therewith by registering passages 3 4L, extending from thegenerator and carbureter, respectively, and 5 a superheater.

6 indicates the usual checker-brick in the carburetingchamber.

7 indicates a passage extending upward from the top of thecarburetingchamber, and 8 a tube which rises from the passage 7 andcommunicates therewith.

9 indicates a stack, which rises from the top of the superheater andcommunicates with the superheating-chamber.

10 indicates acap or valve, which is adapted to close the stack 9. Thevalve 10 is pivoted on a spindle ll, carried by a crank-arm l2, which iscarried by a horizontal shaft 13, pivoted in suitable bearings at thetop of the stack, the arrangement being such that by in the constructionillustrated is adapted toV be supported in the passage 7, as shown inFig. 1.

19 indicates a tube, which supports the oilfeeder 18 and rises throughthe open end of the tube S. The upper end of the tube 19 is secured by abracket 2O or other suitable device and a flexible chain or cable 21 tothe lever'lft, the cable passing around pulleys 22, as shown in Fig. 1.By this construction when the lever 14C is in its uppermost position thevalve 10 will lie over and close the stack 9 and at the same time theoil-feeder 18 will -be in its lowermost or operative position.

When the operator moves the lever 15 down to raise the valve 10 and openthe stack, the same operation will raise the oil-feeder 18, drawing itout of the carbureting-chamber and removing it largely from the heatthereof. It will thus be seen that the oil-feeder is sub- Vjected to theintense heat of the carbureter only when it is in use, and consequentlyits life is greatly prolonged. In order to supply oil to the feeder 18regardless of its position, jointed pipes 23,24 are provided, whichcommunicate with an oil-supply pipe 25 and with the upper end of thetube 19, an angle-valve 26 being provided at the upper end of the tube19 to permit of the movement of the pipe 23.

Under certain circumstances, such as the breaking down of the automaticmechanism, it may be desirable to raise the oil-feeder by hand, and forthis purpose a lever 27 is provided, which is pivoted at one end upon aswinging link 28, suitably supported at the top of the carbureter, saidlever being connected to the upper end of the tube 19 by a pivot 29, asshown in Fig. 1

IOO

While the oil-feeding apparatus is illus-v trated as being movable in avertical plane" familiar with the art and is not limited to the specificdevices or arrangement illustrated and described, except in so far assuch features are Vspecifically claimed.

That which I claim as my invention, and desire to secure by LettersPatent, is j Y 1. In a gas apparatus, the combination of aheating-chamber, a stack therefor, a valve for said stack, agas-chamber, a feeding'device adjustable in said gas -chambe'lg andmeans operated bythe movement of the stackva'lve for adjusting theposition of said feeding device, substantially as described.

2. In a gas apparatus, the combination of a heating-chamber, a stackvtherefor, a valve forsaid stack, a gas-chamber, a feeding device movableinto and out of said gas-chamber,'and `means operated by the` movementrof the 'stack-valve for moving said feeding desubst-an tially asdescribed.

4. In a gas apparatus, ythe combination of a 0"as-chamber, a feedingdevice movable into and `out 'of said chamber, a superheater, a stacktherefor, a valve for said stack, a lever for operating said valve,a'confnectin'g device connecting said lever and 4feeding device and soadjusted that when the 'valve is operated to open the stack the feedingdevice isautomatically moved out of the gas-'c`hainber,and a hand-leverfor moving said feeding device out of said gaschamber,substantially asdescribed.
